commonly referred to as THC.

New Zealand - 41% 16 plus years have tried pot
(Which is 3rd in the world after the USA and Canada. )

Netherlands - 21 % 16 plus years have tried pot
Although pot technically remains illegal in the Netherlands, people haven’t been prosecuted since the 1970s for smoking or growing small amounts for their personal use.
The government also licenses special cafés known as coffeeshops where customers can buy and smoke pot.
The official-tolerance policy hasn’t led to an increase in marijuana use over 40 years worth of data. Education seems to have an effect.
